“It’s a full building that they employ, accounting for 650 workers every day,” Selectmen chair John Connolly said. “We love them.”

Manning, who said that the current valuation for the headquarters site at 130 Royall St. is $22 million, proposed that the five-year extension to the current 10-year TIF will bring in another $6 million in taxes to the town, assuming there is 3 percent regular growth over that period.

“We want this to be win-win for Dunkin’ and the town of Canton,” he said.

Manning said that as part of the mitigation package, Dunkin’ Brands will offer a $25,000 donation to the Senior Center, a $5,000 college scholarship, a business internship for a high school student, and a monthly stipend to police, fire and the DPW.

“This is important to the community,” he said. “It would give Canton more visibility and make it more attractive to other businesses.”
